in the function that renders the button:
function fbc_button() {
if( !osc_is_web_user_logged_in() ) {
echo '<div><a href="' . OSCFacebook::newInstance()->loginUrl() . '">' . __( 'Login with Facebook', 'facebook' ) . '</a></div>';
}
}
it would be nice to find a class appended to the a elemento or the div, so that one can style the button via css:
function fbc_button() {
if( !osc_is_web_user_logged_in() ) {
echo '<div class="fbc-button-container"><a href="' . OSCFacebook::newInstance()->loginUrl() . '" class="fbc-button">' . __( 'Login with Facebook', 'facebook' ) . '</a></div>';
}
}
or maybe add $params = array( ) parameter to that function so that one choose the class to be applied.
